摘要
在本文中，我们研究了智能交通系统（ITS）的能源效率（EE）性能，ITS 是最近出现和发展起来的，通过合作 IRS- 中继网络来保持速度和安全的交通扩展。为了提高能效，中继模型与由多个无源反射元件组成的 IRS 模块进行了整合。我们分析了在 Nakagami-m 消隐信道条件下，不同信噪比（SNR）值下 ITS 的 EE 和可实现速率，这有助于系统在实际场景中的实施。从数值结果可以看出，在信噪比为 100 dBm 时，唯一中继、IRS 和拟议的合作中继-IRS 辅助网络的 EE 分别为 30、17 和 48 比特/焦耳。此外，我们还比较了多中继系统与拟议的合作中继-IRS 和传统中继辅助 ITS 的影响。仿真结果表明，随着信噪比的增加，拟议的合作 IRS-中继辅助 ITS 网络和多IRS 辅助网络都优于中继辅助 ITS。
A novel energy efficient IRS-relay network for ITS with Nakagami-m fading channels
In this paper, we have investigated the performance of energy efficiency (EE) for Intelligent Transportation Systems (ITS), which recently emerged and advanced to preserve speed as well as safe transportation expansion via a cooperative IRS-relay network. To improve the EE, the relay model has been integrated with an IRS block consisting of a number of passive reflective elements. We analyze the ITS in terms of EE, and achievable rate, with different signal-to-noise ratio (SNR) values under Nakagami-m fading channel conditions that help the system to implement in a practical scenario. From the numerical results it is noticed that the EE for the only relay, IRS, and proposed cooperative relay-IRS-aided network at SNR value of 100 dBm is 30, 17, and 48 bits/joule respectively. In addition, we compare the impact of multi-IRS with the proposed cooperative IRS-relay and conventional relay-supported ITS. Simulation results show that both the proposed cooperative IRS-relay-aided ITS network and multi-IRS-aided network outperform the relay-assisted ITS with the increase in SNR.
